A new approach to the construction of a radio altimeter based on J-correlation processing is proposed. Its operation is based on the transformation of the modulation index of the probing signal into a functionally dependent on the space-time delay. The structural scheme of the device is given, and the signal processing of the device is analyzed. The characteristic of the altitude meter is obtained. For the radio altitude meter of low altitudes (1500 m) the FM signal modulated by a single-tone harmonic oscillation with the following parameters is used: modulating frequency 70 kHz; width of the signal spectrum not more than 1 MHz, measurement accuracy not worse than 0.15 meters.
